JellyfishOPP is/will be an open-hardware measurement device and programmable power supply designed to provide advanced, bidirectional power measurements, power optimizations, and battery profiling/simulation. It primarily targets developers of ultra-low power devices such as IoT sensors and wearable electronics, while also serving engineers and hobbyists. It is a portable USB device that can be controlled through a host computer or smartphone app. Additionally, it will feature a simple on-device user interface for basic functionalities, eliminating the need for a host device in certain scenarios.

This talk will cover the design decisions and the current development status of the device. The main web page containing the info and links to all of the development updates can be found at https://hyperglitch.com/jellyfish.
